I contacted Hi-Tech Air after hours. It wasn't an emergency, so I told their answering service I could wait. First thing the next morning, I got a call from Hi-tech Air Conditioning and an appointment got set up the same day. Before the tech came out, I received a text with a picture of who I could anticipate showing up to do the work. It was all done in a timely, smooth, and seamless way. The issue was resolved the same day. I highly recommend High-Tech Air Conditioning.

From getting a text message that Casper the tech is coming to saying goodbye and getting email of the job, it's one of the best experiences I've encountered. Casper was able not only to professionally answered my questions but explained it in plain English! He's a true Pro at what he does. I'll definitely recommend Hi Tech! And by the way, Jennifer in customer service office was very helpful and got me an appointment next day despite a very busy and hot week.

Dave Scott was excellent. He knew what he was doing and was very efficient and professional. Would definitely recommend Hi-Tech Air Conditioning, Inc. Update 11/30/2020: Piece needed to fix the air conditioning system came in and Dave came back to finished the job. He is awesome. Thank you again for your hard work and dedication.

I have used Hi-Tech for years as my service provider for any HVAC issues and can't say enough about the professionalism and reliability. Recently, we had an issue that required an after hours visit. To my surprise, Bob, the owner, showed up at my front door which was unexpected but he wanted to make sure to address any immediate needs b/c the after hours tech had a few calls in front of me and I have a family member that requires AC for a health condition.

Fast forward to the replacement of the defective piece of equipment. Kari and the office staff couldn't have been more accommodating. They were able to get the replacement part ASAP and fit me in to the schedule before the weekend. Casper was at my house promptly on the day of the scheduled appointment. He was extremely professional and made sure I understood what caused the problem and ensured that everything was working properly.

After the visit, I had what turned out to be an unrelated plumbing issue that Casper offered to come back later that day to address (after a full day of other calls). I told them that it could wait till the next day, which again happened to be a Saturday. Casper made time on his day off to come back to see if he could help clear the drain line for me. Turns out my issue required an actual plumber to clear the larger drain but also shows the caliber of the people you work with at Hi-Tech. From top down, you can trust that Hi-Tech will listen to your concerns and truly makes you feel valued as a customer.

From the moment I called to the technician (Casper) arriving was less than 10 minutes. He fixed my problem, was honest about my future needs, he gave me future options but wasn't pushy. I'm very impressed with the responsiveness and care that Casper demonstrated! I will recommend them and will call then again when necessary - outstanding service!
